Dash Valve
Bendix

A compact dash valve assembly acts as the central pressure control element in tractor-trailer air-brake circuits, translating operator input into regulated braking pressure. It provides distinct tractor and trailer trip settings, including a tractor trip of 30 psi and a trailer trip of 35 psi, with a trailer override at 25 psi for override configurations. The design accommodates a mounting dimension of 0.31 in and 3/8-PT thread ports on supply and delivery paths, offering four ports to coordinate service and release functions. Rated for maximum operating temperatures up to 200 Deg.F and minimum -40 Deg.F, the unit remains reliable across extreme climates, essential for long-haul operations. Although shipped without buttons, its simple footprint reduces maintenance complexity and minimizes potential leak points. VMRS code 013-010-014 places it in the valve family that governs tractor-trailer trip controls, and the four-port configuration supports various line-routing schemes. Category 41532 reinforces its role in the valve-and-controller subset of the air-brake system, with compatibility across Bendix actuation modules and standard 3/8 in piping networks. This component is a practical choice for fleets prioritizing precise trip-override behavior and robust cold-weather performance.
